This invention has reference to machinery for making cup wafers of various shapes, wafer. biscuits, and the like, of the kind in which a rotary part containing a plurality of sets of cooking moulds or plates are mounted on a revolving body or part, and areadapted to be rotated intermittently, and when the mouldsor plates are opened, and a cooked batch of cup wafers, cones, or the likeisremoved from same,.better or like liquid, from which these articles are made, is supplied automatically to the moulds or cession, these parts are similarly moved'back.

over themoulds or plates, and the operation described. is repeated.

I For convenience of description, the invention will be described as applied to a machinefor'making cup wafers,that is wafer biscuits of conical or cup form adapted to receive ices. confections,.or the like.

In. this machine, the cooked article removing devices referred to are so arranged or formed that they can be moved down into the interior of the cooked cups or cones, and

engage. the interior of same;'and then they are moved upwards, and lift the articles out of the moulds, and move them over. into the position of reception, when they are adapted to release them. Furthermore, the cups or.

cones are: freed from the moulds bythe moulds being in parts, and adapted to be automatically opened; that is different parts.

are'movable in relation to each other, so that when they are so moved,say from pivot or point below, the mould parts will move. away from another, .and from the ex.

terior surface of the cooked cup or cone, thus freeing. it.

The extracting. parts above describ'edare.

machine constructed and adapted to operate inthe manner above set forth.

In these drawings, Figure l is a side elevation of the machine; Figure 2 is a cross section of same; Figure 3 isa plan, Figure 4 is a detail of the cup or cone removing device.

Figures 5, 6 and 7 are side elevation, plan, and end view of'the plates or. moulds, andhthe partsimmediately connected there wit I The machine is adaptedto be worked by power, and l is the primary shaft by which power is transmitted 'to the machine.

This power is transmitted to the mechanism of the machine through a worm 2, v and a worm wheel 3 on ,the shaft 4, on

which are also fixed cams 5, 6 and 7, which through levers or the like, transmit motion to the various parts or mechanisms of the machine; namely, the batter or like liquid feeding apparatus, the cup or cone extracting and removing. mechanism,.and the plate opening. and closing mechanism.

The rotary mould carrier frame consists of two plates. ordiscs- 8 between and to the inner faces of which the moulds are. fixed, parallel withwhich is a baffle plate 9 carried from one of the plates 8 by bracket 10, to which the flanges. ofthis plate 9 are fixed. These. brackets. also serve as the pivot carriers of the top movable plates of the moulds.

The discs or plates. 8 are mounted on a shaft 11 at one. side, which is supported in a bearing 12; and theother plate 8 sup- 1 by r'crossibars. 19, which are supported by a frame of T form markedw20, the lower 'por- "portedbearing' l3, and'such bearings 12 and 13 are formed on the main stationary frame plates '15 of the machine, which exsides to thetwo plates 8 which carry the moulds,; and the upper parts or edges of the moulds-are tapered, and normally. fit,

-- and restin tapered. recesses in the top plate i V is revolved step bygstep-'in the case shown 18 of 'thef'mould box 16; and all these separate moulds are carried at their lower ends tion of which is moved up and downin a bracket 21 as hereinafter explained. V

The whole frame8 with the attached and carried mould boxes, and parts connected with them for operating the moulds proper,

one eighth of a revolution-by means of a disc '24-fixed on ,the shaft l1, and operated from the'wor'm wheel 31by arolleron same, marked 2 5,fwhich asit comes round by the V rotation offthe wheel 3, engages :with one ofthe' notches 26in 'thefaceof the disc 24,- and so 'moves itaportion of; acircle, name .ly, th. After thedisc and frame- 8 are so I" moved,theirollerfleaves the notchor recess 26,"'one of the mouldsor plates being then in the up ermost" horizontal position, in

which Fit 1 will be i'opened as hereinafter described, and the contents removed.

.When'in this position, the first operation is 'to remove the upper or coverplate 27 of; the mould, which is hinged to the brackets 10 by the hinges 28; and thisis effected by a lever-3O pivotedon the hinge 28, and-having a de ending ,grooved'e'nd 81, into'the groove 0 which a fitting 32 on-the' cover 271 ofthe mould enters, wheno-it'arrivies in this position, so; that when the opening lever is J rocked on 'its supporting pivot 28 by meansas hereinafter described, the cover 27 willibe lifted up about its hinge 28, so as to' completelyuncover the moulds proper;

the top plate 27 having previously been un-- locked part of itslocking latch 33-having come into thebamgroove 33 "as usual in this type-of'machine. 1;

The'lever 30fis operated bya fixed on a spindle'35jcarried in'the brackets 35? fixed on the frame 15,the crank operatingthe leverthrough alink 36; while the @crank shaft 35 is "operated" by. a rack 37, V engaging want toothed pinion on 35, a'nd which isfoperated from the grooved face cam 6onthe shaft'4, this cam operating on.

a lever38, and a link 39 connecting 38 with 37;"1 he rack 37 is guided and works up and down in a guide bracket 40, fixed on the outside of the frame 15.

When in this position the cup wafers or conesare removed, by a number of 3 spring prong or finger devices 43, fixed in a plate 44, which is carried by two arms or levers 45,

fixed on two rocking axlescr shafts 46, carried on the upper part of the frame, and worked by two toothed quadrants 47 fixed on these shafts. These quadrants are operated by a common'corresponding toothed quad-, vrant 48 fixed on a shaft49 which is rocked circularly to and fro by the cam 5 through a lever 50 pivoted at. 51, a'link 52,. and an arm 58. fixed on the spindle 54," on which also is fixed an arm or ;lever 55, connected with an adjustable crank arm 56 on the face of the quadrant .48, and connected with same by the connecting rod 5 7.- Thus, as the lever 5 0is worked by. the cam 5-,"so willthe carrier plate44 and fingers 43 in the Qfirst portion of their action, bemovedover and.

into the conesin the moulds, and their hook 7 ends made to engage the inner surface of thecones, they being slightly compressed by pressing themdownwardly into the cones; and after this, the moulds themselves which "are splitori in halves, are opened, so asfto liberate the cones, and thereupon the, reverse action of the finger carrier plate 44 takes place,and it is moved upwards and over into the position Sl10WIl 1n full hnes 'ln'Figure 3, when the cones are subsequently released from'the fingers as hereinafter described.*. v i 1 Regarding the operation of openingthe mould cones 17, they are as shown, made in halves, all the halves on each side of the row of moulds being in one, and the: two sets of halves. are carried on a hinge rod 19,

and they are all lifted together intheir box 16 through T-shaped carriers 20, by means of a lever 60 hinged at 61, and connected to the'lower part of the carrier 20, and its other end to abar 62 (one of whichvis car ried in each of the moulds) the endof which normally projects above the top of the mould as shown, and passing through the cover 27. When the mould is open, this bar or rod 62 is depressed, and thereby'the moulds are raised and open the moulds; the depression bein effected by a lever 63 mounted on the sha t 64, and operated from therocking shaft 54 by an arm 65. fixed thereon, through a connecting rod 66, and an arm 67 fixed on the shaft64, on which the'arm 63 is fixed;'so that, as this arm 57, I is moved'up and down, the lever or arm 63.

is moved up anddown and 'actuates the bar or rod 62. r

1 To cause thetwo' halves of each mould 17- to move away from each other in they freeing action above described, a pin 68 is fixed on the inslde of the mould box or carr1er-16and works in OOIlIlGCtlOlIWltll each row of moulds and it projects into a wedge 1 shapedjopening 69 in the side of the mould no I a 76 in the end of the lever 74*.

adjacent to it, so that when the moulds are moved up as described, the pin will press on the inclined sides of this gap, and so press the two halves apart, in which action also the upper inclined faces or edges of the moulds will be lifted up out of their inclined circular seats inthe top plate 18 of the mould box, as shown in dotted lines in Figure 7. 7

Regarding the releasing of the cones or cups from the fingers after they have been removed fromthe mould, a thin releasing plate 7 O is employed through holes in which the inclined upper parts of the fingers 43' pass, so that if this plate is pressed down,

the edges round the holes in same press on the inclined parts of the fingers, press them together, and so remove their lower engaging tips or hooks from the interior of the cones, and so free them; and this action is effected by pins 72 on the plate 70, which are carried up through the plate 44, and are acted on by levers 73 fixed on the pivot pin 74, carried by the plate 44, and having fixed on it a lever 74*, which is actuated by a cross bar 75 carried by the lower lever 45, this bar acting at its centre on a screw pin Thus when the lever 74 is lifted, the levers 73 press the plate 70 down, so that the fingers release the cones or cups. 7

The lifting of the plate 70, after its depression, is effected through springs 71 surrounding the headed pins 72, which are fixed to the plate 70, and pass through the plate 44. Thus when the plate 44 is free, the springs 71 press the pins and the plate 70 up, and so allow the fingers to expand.

After the cones or wafer biscuits have been removed from the moulds, and the latter lowered by the elevation of the lever or arm 63, the moulds are recharged withthe required quantities of batter or liquid; and this is effected'by an automatic supply apparatus generally marked 80, which in itself is of knownkind, and which when moved over the moulds will'automatically deliver the required quantities of liquid into {all the several moulds, the quantity being a pre-determined one..

The charging apparatus is carried by pivoted carrier arms 81, fixed on the rocking pivot shafts 82, carried by bearings on the upper part of the frame. On theshafts 82 are fixed toothed quadrants 83, which mesh with a common toothed quadrant 84 fixed on the shaft 85, fixed on the frame 15; this latter quadrant being worked from the cam 7 through a lever 86, and a connecting rod 87, which is fixed to a crank arm 88 adjustably fixed on the quadrant 84.

After the moulds have received the required quantity ofbatter, the cam 7 will then operate the arms 81, and lift them, and so lift the automatic supply apparatus 80 intoits upper positionas shown inthedrawing; and; thereupon the cover 27 is: moved downover the top of and: closes the moulds by means ofthe-lever' 30 ,fand thecatch 33 willlthen fall underthe engaging projection of the mould box, which it is free to de by;

gravity, being hinged from the engaging part 32; andthen the whole mould frame" islrotatedione eight of a revolution by means of the disc, 24, andTitsjoperating ca'mand ways open to and being acted upon by the heat within this chamber, the escape of heat from which cantake place through suitable holes in the plates or frames 8.

Vent holes are provided in the top plate 27, so as to permit of the vapour or steam driven off in the cooking of the material, to bereleased and pass away. 7

All the half moulds of a row of moulds are in one casting, and the outer edges are scalloped; and the top plate of the mould box is correspondingly formed, as shown; and in the top plate there are holes 92 which. will come under the vent holes 93 in the cover 27; and between the sides of the box 16, ribs 94 extend from side to side so as to form several elongated spaces in this box, within which the moulds proper 17 are disposed.
